Voltage and Current Conventions
... • Voltage is a relative measure of the Energy of a charged body at point A with respect to its energy at point B. • If it requires Energy of amount U to move a body having charge Q from point B to point A, then we say that there is a “potential difference” between points A and B of U/Q = VAB volts. ...
